Conditions at Baltrum in March
March: The Shift Begins, Yet Winter Still Grips the Lineup
A faint sigh of relief ripples through the Baltic air as the first, tentative warmth of spring arrives. The average swell height relaxes to 1.4m (4.6ft), and the period tightens to 6.5s. The wave direction still pulses from the NW-NNW quadrant (a combined 26.5% of energy), keeping the beach active. The wind patterns are still wintry, with the southwest and WSW sectors clocking in as the most frequent (9-10% each), but this also means more days with an offshore or sideshore component. The ideal wind frequency ticks up to 12%, still low, but when the sun finally burns through the marine layer, the conditions can become surprisingly clean. Water temp sits at a chilly 5.1°C, so 5/4mm hooded suits are still mandatory. The average swell of 1.4m is right in the sweet spot of 'pumping' on the heavy scale of the North Sea - but the short periods mean you need to pick your days. A strong cold front can still produce a firing, 2m+ swell, but it likely comes with teeth (storm-force onshore winds). Stick to the S-SW wind days, and March offers the last truly powerful surf of the season.
